I saw a sport of Mammy growing at work. Mammy is planted in mass here, and one particular plant had a distinct sport growing from it. I rooted it and planted it out. A few questions surrounding the sport: 1. Is a sport that looks totally different that unusual? 2. Does the sport always revert back to one the original parent plants if say, Mammy is a hybrid? 3. Will this sport revert back to Mammy at all? 4. Will a Mammy exhibit different types of "sports" or will all of the sports from Mammy look pretty much the same?
